Description
Technical field
This utility model relates to RCCB technical field, is specifically related to a kind of chopper leakage function construction of switch and has its RCCB.
Background technology
Chopper is usually and connects in circuit, and when occurring overcurrent in circuit or being short-circuited, circuit is cut off in chopper automatic trip, thus provides power-off protection for circuit and equipment.Mostly existing chopper is breaker of plastic casing, in order to ensure product quality, it usually needs enable the insulated barriers between any biphase electrode slice to stand the high pressure of some strength and the most breakdown；Shell is moulded again owing to the wiring board for controlling circuit breaker trip is typically to be welded on, and it is electrically connected with power taking with two in above-mentioned electrode slice, in order to test the insulating properties between this biphase electrode slice, in order to avoid high-voltage breakdown wiring board, generally require first by dismantling circuit board, the insulating properties between the most biphase electrode slice are tested, wait after being completed, also need to again weld on-board the circuit breaker wiring board plate, and the leakage function of measurement circuit plate again is the most normal.Seen from the above description, in order to finished product chopper carries out insulating properties test in prior art, need to destroy the chopper finished product made, after being completed, also again to assemble, this not only wastes time and energy, and is also difficult to all of chopper all carries out the test of these insulating properties.
Chinese patent literature CN104979142A discloses a kind of electrical apparatus release and has the chopper of electrical apparatus release, and specifically disclose a kind of measurement structure, as shown in Figure 1, including the measurement button 03 being telescopically located on the second wiring board 02, measurement button 03 has stop tab 08 and two executive items 04, it is arranged with back-moving spring 05 on one executive item 04, one end of back-moving spring 05 is fixing with measurement button 03 to be connected, the other end is resisted against on first line plate 01, and is arranged on first line plate 01 and the electroconductive elastic sheet 06 relative with power taking part 07；When needs normal operation of circuit breaker, press down on and rotate measurement button 03, executive item 04 is made to press down on the electroconductive elastic sheet 06 being arranged on first line plate 01, it is deformed into downwards under the pressing effect of electroconductive elastic sheet 06 executive item 04 and contacts with power taking part 07, so that first line plate 01 and the second wiring board 02 electrically connect with power taking with the biphase electrode slice of chopper, stop tab 08 is followed the rotation of measurement button 03 and is rotated and be stuck on housing, thus keeps this connection status；When needing the biphase electrode slice of chopper is carried out insulating properties test, reversely rotate measurement button 03, stop tab 08 is no longer stuck on housing, back-moving spring 05 discharges elastic force and promotes measurement button 03 to move upward, executive item 04 no longer presses electroconductive elastic sheet 06, electroconductive elastic sheet 06 resilience under the effect of its own resilient, no longer contacts with power taking part 07, and the electrical connection between first line plate 01 and the second wiring board 02 and the biphase electrode slice of chopper disconnects.
Although the biphase conducting strip of wiring board Yu chopper can be carried out closed and disconnected operation in the case of not dismantling wiring board by the technical scheme in above-mentioned patent documentation, but it by means of and is arranged on the electroconductive elastic sheet 06 below first line plate 01 and power taking part 07, cause total the loosest, easily interfere with other parts, and be unfavorable for the miniaturization of equipment；Additionally, said structure needs to rely on the elasticity of electroconductive elastic sheet 06, and in order to ensure elasticity, the thickness of electroconductive elastic sheet 06 is the most relatively thin, such as occur that electroconductive elastic sheet 06 all can be caused damage by electric spark during long-time use or use, and then cause service life of equipment to reduce.
Utility model content
Therefore, the technical problems to be solved in the utility model is to overcome measurement architecture of the prior art loose, easily interfere with other parts, it is unfavorable for device miniaturization, and too much rely on the elasticity of electroconductive elastic sheet so that relatively low technological deficiency in service life, thus it is little to provide one to take up room, compact conformation and long-lived chopper leakage function construction of switch.
